[Dovecot] Configuring SPECIAL-USE Dovecot 2.0.9

Hi All,

I'm trying to configure Dovecot 2.0.9 to support Outlook 2013.

As I understand it, I need to configure XLIST. I have added

imap_capability = +XLIST

to 20-imap.conf

When I try to query the IMAP folders I get an error "An IMAP command Failed". Looking at the logs I get XLIST Command not found.

I can only assume that I'm missing something in the configuration.

Any help would be greatly appreciated

Thanks

Keith
